Ac compressor wont engage

[smileymechanic92]

Hi all, got a M6800 with ac issues. At first compressor was constantly staying engaged, high side reading 350psi and low 75psi. As soon as I unplugged low pressure switch clutch disengaged. Order new switch(off brand, wanted to be cheap) and replaced. Now clutch won't engage. Pulled vacuum and followed recharge procedures. Am I missing something, is there a fuse or relay ?

Check wire(s) connected to clutch for 12 v when ac controls are turned on. If you have 12v but clutch doesn't engage, odds are that clutch is bad.
